IMPROVEMENT IN BLIND-SLAT RETAINERS.

Specification forming part of Letters Patent No. 217,464, dated July 15,1879; application fnled November 1`1, 1878.

To all whom t may concer-n:

Beit known that I, PETER N. HoRsLEY, of J ersey City, in the county ofHudson and State ot' New Jersey, have invented a new and usefnlImprovement in Windo\v-Blind-Slat Fasteners, and that the following isa'full, clear, and exact description thereof.

My invention relates to a device for holding window-blind slats eitherfirmly closed, to prevent the wind blowing them about and causing anunpleasant rattling, or while par` tially open to prevent the insertionof a hand fron the outside for the purpose of unfastenin g the blind-fa-Stening, 85e. For this purpose various devices have been employed,all different in their construction and operation from mine.

The invention consists of two plates of metal (or other equivalent) sohinged together, bev-A eled, and fastened on the corner edge of ablind-frame as to allow the pointed edge to enter into a notchedmetallic plate fastened on the edge of one of the slats, which pointededge being so placed therein holds the slats at right angles, and whenraised from that position and placed in other positions, as the turningup or down of the slats may require, holds them firmly in such positionand immovable (when turned down) from the outside, thereby preventingthem from being opened from the outside, all as hereinafter is morefully described and claimed.

The accompanying drawings illustrate the lnanner of carrying out myinvention.

Figure l shows two hinged plates, A and B,

the former of which is attached to the frame. The other is beveled onits edges, as shown by letters a and b; letter D being a knob placed on`plate B, to move and alter its position after-plate A has been attachedto the side of the blind-frame, (represented in Fig. 3 by letter E.) Y fFig. 2 represents a metallic plate, C, which is lto be fastened on theedge of one of the slats, as is shown in Fig. 3, having one end notched,as shown at c, to allow the pointed edge of plate B to drop into it whenit is desirable to have the slats held at right angles.

Fig. 4 represents a small flat spring, G, with one end turned down,which is fastened on the side of the slat F with a pin or screw. Saidspring is intended to hold plate B securely against the edge of theblind-frame, thereby making the fastener even more secure from theingress of a hand or instrument to effect an entrance when the slats areturned down.

"Having thus fully described my said invention, what I claim as new, anddesire to secure by Letters Patent, is-

4In a window-blind-slat retainer, the conibination of the hinged platesA B, ,the former being attached to the frame, and the latter providedwith beveled edges a b and knob D, with the plate C, having notch c, andthe spring G, substantially as and for the purpose set forth.
